Q: What do I need to install V Expressions expansions?
A: Installation requires MIDI connectivity from your personal computer via Firewire, USB or a PCI based midi interface. Alternatively, many stand alone sequencers can be used. (please see Roland's directions for sequencer usage in your TD-10 owner's manual)
